Hydraulic fracturing using high-boiling fraction of oil as a fracturing fluid

چکیده

Background: In recent years, there has been a trend towards deterioration in the structure of residual reserves at fields Kazakhstan. A significant part is located low-permeability reservoirs and zones not covered by flooding. The main factor negatively affecting productivity efficiency development heterogeneity oil reservoirs.
 Oil-saturated formations are an alternation permeable oil-saturated sand or limestone impermeable clay dolomite layers, lenses interlayers. Up to 1020 interlayers can be distinguished within reservoir, which indicates strong compartmentalization reservoirs. Due complexity deposits, it very difficult impossible ensure complete drainage entire volume deposit coverage displacement water into production wells through injection wells.
 Aim: Increasing recovery cost-effective way.
 Materials methods: Experimental studies processes impact on bottomhole formation zone with high-boiling components were carried out using laboratory machine for diamond drilling, installation determining permeability rock terms liquid gas, viscosity, pumping fracturing fluid reservoir model.
 Results: As result applying hydraulic method components, possible increase significantly recovery.
 Conclusion: geological multi-layer oilfields, water-based gel fluids flow considered ineffective due adsorption gels long molecules pores swelling particles when they interact fluid.

Energy Analysis of Hydraulic Fracturing

In this paper, numerical simulations of circular boreholes under internal hydraulic pressure are carried out to investigate the energy transferred to the surrounding rock and the breakdown pressure. The simulations are conducted by using a micromechanical continuum damage model proposed by Golshani et al. (2006). The simulation results suggest that the borehole breakdown pressure and the energy...

Differentiating Applications of Hydraulic Fracturing

Hydraulic fracturing has received abundant media attention in recent years due to a rapid increase in the use of the technique in combination with horizontal drilling technology to produce oil and gas resources from tight reservoirs. Hydraulic fracturing techniques are also used in a variety of other applications that are unrelated to oil and gas production, includ‐ ing tunnel and dam construct...

Numerical Modeling of Hydraulic Fracturing in Oil Sands

Hydraulic fracturing is a widely used and e cient technique for enhancing oil extraction from heavy oil sands deposits. Application of this technique has been extended from cemented rocks to uncemented materials, such as oil sands. Models, which have originally been developed for analyzing hydraulic fracturing in rocks, are in general not satisfactory for oil sands. This is due to a high leak-o...

Complex Fluids and Hydraulic Fracturing.

Nearly 70 years old, hydraulic fracturing is a core technique for stimulating hydrocarbon production in a majority of oil and gas reservoirs. Complex fluids are implemented in nearly every step of the fracturing process, most significantly to generate and sustain fractures and transport and distribute proppant particles during and following fluid injection. An extremely wide range of complex fl...
